★給好奇孩子的「超入門單位圖鑑書」★
你聽過公尺、公升、加侖，
但是你有聽過海里、光年、流明、勒克斯這些單位嗎？
課本上常出現、令人頭痛的單位詞，一本澈底搞懂！
輕鬆培養孩子的數感及量感！

        你知道最古老的「單位」是什麼嗎？
　　想知道測量星球之間的距離，要用什麼單位嗎？
　　公尺、公里、公分、毫米、碼，怎麼換算才正確？
　　「馬力」的單位詞起源，真的跟馬有關係嗎？
 
　　本書涵蓋14個領域、78個單位詞，
　　將枯燥乏味的單位擬人化，變得親切有趣易懂，讓孩子不排斥學習。
　　認識各種單位的起源、定義、用途及換算方法，
　　從日常點滴累積科普素養，擴展對世界的眼界！
 
　　★從日常生活中認識單位，知識大躍進！
　　「媽媽，這根樹枝有多長呢？」
　　「爸爸，這塊石頭有多重啊？」
　　「老師，那位選手跑得多快呀？」
 
　　當我們要告訴別人某個東西有多長或多重時，如果只說「大約這麼長」、「大約這麼重」，無法表達出正確的長度及重量，因為每個人的感覺都不同，如果要充分溝通，就必須有一個「基準」，這個基準就是「單位」。
　
　　原來在遠古時代，人們還曾經使用手掌、腳掌、手臂……來測量呢！但是這樣的測量方式不夠準確，所以不同國家開始建立屬於自己的測量方式與單位，隨著國際交流越來越密切，終於出現「國際單位制（SI）」的發明與認定，全世界有了一套測量的標準，再也不用為了測量大小事而爭吵啦！
 
　　★一起來認識讓生活更方便的「單位」 ！
　　‧帥氣「公尺小哥」你可以叫我單位界的一哥，我出場的地方多到數不完，身高一公尺的人，張開手臂也差不多是一公尺喔！
　　‧秀氣「毫克小姐」秤量藥品是我的工作，可以準備一粒米感覺我的分量喔！ 
　　‧淘氣「秒寶寶」我是表示時間的基本單位，一天大約有8萬6400秒，很酷吧！
　　‧美麗「瓦特大姊」我常運用在微波爐和電燈泡方面，用電流╳電壓，就能算出我有多少了！
　　‧調皮「西弗小鬼」我是表示放射線對生物的影響程度，醫院的X光也是放射線的一種喔！
　　‧可愛「牛頓小妹」我是表示力量的單位，將100克重的物品放在手心時，下壓的力量大約就是1牛頓喔！
 
　　萬物都能量，從具體到抽象，各種生活事物都需要經過測量，看似難記又難懂的測量單位，原來我們每天都需要用到它！因為有了「單位」，我們的生活才會變得更加便利，趕快翻開本書，變身能靈活運用的單位達人吧！

Great Bone for aggressive chewers but watch the wear & tear
I’m extremely happy I found Benebone Bacon Flavor Large Wishbone for my puppy who is an aggressive chewer. As the packaging reads this is a durable nylon. My puppy chewed the bone down to what you see in the picture within 3 days. It’s easy for him to handle. He loves the bacon flavor. He immediately took to it as soon as I gave it to him & off he went to work. I did check with my Veterinarian first to inquire if this was a safe bone & she assured me it was. She did advise to be aware of the wear & tear on the bone & toss when I felt it was time. I honestly wouldn’t of known when. I’m happy I took the time to read the inside of the packaging this bone came in. It referred me to the benebone website which showed pictures of bones-which I attached- that reflect the wear & tear & when it’s time to toss. There are the 3 categories of “Light Wear,” Moderate Wear“ & “Heavy Wear.” You’ll see the written description next to each. This I found very helpful, therefore I wanted to include it in my review, in hope of helping you. By the looks of my current bone it’s in between moderate & heavy wear. The large is costly, I feel, but it 100% occupies my puppy. It’s his favorite “toy.” I’ve only had small shavings come off since he’s chewed it. Nothing major to clean off the couch where he lays. Stuffed toys are a thing of the past now. I’ll continue to buy once it’s time to toss this bone because he loves it so much. I also love that Benebone is Made in the U.S.A.! I definitely recommend! A heads up! If you click on their store on the main page of this bone you’ll find other shapes of the nylon bone as this one. This Benebone won’t disappoint. Take the time to read the packaging. It’s informative & cool!

Very durable and long-lasting, great for strong chewers, gets rid of plaque in older dogs
I have a seven-year-old golden retriever who was never a strong chewer, she liked gnawing on toys and dental “bones” and destroyed shoes and a carpet when she was a puppy but it was never her favorite activity. Then I adopted two puppies of indeterminate breed, but likely Plott Hound and Lab, and they are aggressive chewers and want to chew on everything. I tried all kinds of teething things, as teething seemed to bother them more than any of the other four dogs I’ve had, and all were destroyed quickly, like they were treats instead of supposedly “long-lasting” chew bones. I tried these bones after I happened upon them on Amazon, and I could not be happier. My dogs contentedly gnaw on these for extended periods of time, obviously in heaven as they do so, and sometimes it’s the only way I have time to get anything done. When they were teething these definitely helped them with teething pain, and now they still want to chew on them every day. They can hold them easily and sometimes the puppies even share a bone due to the unique shape. My Golden had lots of plaque and nasty buildup on her teeth and was headed for needing dental cleanings under anesthesia, but now her teeth are sparkling white without a speck of plaque thanks to these. The bones have worn down over the course of eight weeks, but very gradually and not ever in pieces. Yes, the ends become prickly and are definitely not fun to step on, but I don’t let them chew on them outside to reduce them collecting dirt and rinse them every few days to get rid of whatever is on there. I have watched carefully for any signs of irritation in my dogs’ mouths or teeth issues, and have never seen any blood on the bones even after my dogs have determinedly chewed on them for an hour. They LOVE them, and because they are the only bones I have found that last longer than five minutes for my aggressive chewers, hold their attention for an extended period of time, and get rid of all the plaque on my older dog’s teeth, I HIGHLY recommend them.

I love this and so does my dog
I got one of these, to try out on my super chewer pit mix, back in early April, it's now the end of June and she's still chewing it every day, almost all day! It has gotten smaller as she's chewed it but it's not broken or splintered or hurt her teeth! Just make sure to get the right size for the dog. Small dogs maybe the smaller ones but a big girl like mine needs the large or bigger. Idk if she gives a darn about the taste or smell of it but she loves chewing on it, and hasn't felt the need to chew my shoes or wtfe since she got this. I like it so much I got more for my friend who also has a few super chewers and she gives good reports on them too. Her chewer dogs have stopped destroying her house in favor of these chews. Just try not to step on them in the dark, cause that s#!t hurts, BAD! Lol especially if you step on the chewed parts, where its rougher. The attached Pic is showing how badly she's chewed it in almost 4 months! The chewing calms her anxiety and gives her something to focus on when she's too excited, especially late at night. I will be getting more of these for her. even thinking about trying other shapes to see if they hold up as well as the wishbone shape does. She's an adult dog so idk if these would be OK for puppies, as it might Crack their teeth.
